Some winter active flies from snow and caves of Vârghiș, Romania

Abstract

This paper attempts to fill the gaps in knowledge about the biodiversity of some winter-active fly families from snowfields and caves in Vârghiș, Romania. A total of 15 fly species were recorded from caves and 9 species from snowfields. Exechiopsis (Exechiopsis) pseudindecisa Lastovka et Matile, 1974 and Rymosia placida Winnertz, 1863 from caves and Mycetophila mitis (Johannsen, 1912) (all Mycetophilidae) from snow represent the first records for Romania. Habitus photographs of these three species are provided.
